I've been browsing internet for a few hours, I've checked all threads in your forum too without any luck..
The problem is, when I try to send a sms, it says "Service centre address has not been set. In Control panel, tap 'Messaging accounts' and select SMS tab to add it.". But when I go to mess. accs I can not tap SMS or Area, only Email or MMS.
Any suggestions on this one?
